CREDIT CARD LIST VIEWER Filed Sept. 50, 1965 //7 /5 QL vgnaw ,imumw- I i i 1 INVENTOR United States Patent 3,382,594 CREDIT CARD LIST VIEWER Donald N. Volger, 4000 Hollywood Blvd., Los Angeles, Calif. 90027 Filed Sept. 30, 1965, Ser. No. 491,608 3 Claims. (Cl. 40-68) ABSTRACT OF THE DISCLOSURE A clear plastic, tubular device to hold a sheet of paper containing a list of rejected credit cards rotatable in a pair of brackets.

This invention relates to movable viewers, and more particularly to a rotatable viewer for a list of defective credit cards for use in gasoline service stations and the like.

In the past shopping guides such as that shown in US. Patent No. 2,687,589 have incorporated rather complicated rotatable viewers.

In accordance with the device of the present invention, a credit card list viewer is provided with very few uncomplicated component parts, including a pair of leaf spring supports, a transparent cylinder and connection means at the end of each support rotatable thereon for holding the ends of the cylinder.

In accordance with a feature of the present invention, a cup is provided at each end of each support, the cups facing each other. The cups are rotatably mounted about their axes on' the supports. The transparent cylinder then has its ends locked in the cups.

According to another feature of the present invention, the cups are provided with gripping means on the interior thereof to prevent rotation of the cylinder in the cups.

According to a further feature of the present invention, the supports are bowed in slightly to supply an axial bearing load on the cups to prevent their rotation without the application of a rotative force thereto.

The above-described and other advantages of the present invention will be better understood from the following description when considered in connection with the accompanying drawings.

In the drawings, which are to be regarded as merely illustrative:

FIG. 1 is a perspective view of a viewer constructed in accordance with the present invention;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a transverse sectional view of the viewer taken on the line 33 shown in FIG. 2; and

FIG. 4 is a longitudinal sectional view through the viewer taken on line 4-4 shownin FIG. 3.

In FIG. 1 a viewer is shown mounted on a service station cash box 11. Viewer 10 includes standards 12 and 13 which are fixed to cash box by screws 14. Standards 12 and 13 are braced from one another by a bracket 15. Bracket 15 is fixed to standard 12 by metal screws 16 and to standard 13 by metal screws 17.

All of the structures surrounding the upper end of bracket 13 are identical to those surrounding the upper end of bracket 12. For this reason, in FIG. 4 only those structures surrounding the upper end of bracket 12 will be described.

A cup 18 is rotatably mounted on bracket 12. Cup 18 has internal projections 19 which frictionally engage the ice ends of a transparent plastic cylinder 20. Cylinder 20 may be made of clear plastic or celluloid or the like. Cup 18 has a boss 21 that bears against bracket 12. Cup 18 has a shaft 22 that projects through a hole 23 in bracket 12. Cup 18 is retained on bracket 12 by a conventional snap ring 24.

Standards 12 and 13 act as leaf spring supports. They are normally bowed in slightly. This places an axial bearing load on cups 18 and keeps cups 18 in a fixed position unless they are rotated manually. Projections 19 in cups 18 keep cylinder 20 from rotating in cups.

Normally numbers of credit cards not currently valid are printed on a rectangular sheet. This sheet may be rolled and assembled inside cylinder 20. This may be done by springing standard 12 to position indicated at 12' and completely removing cylinder 20 from cups 18. The list of credit card numbers may then be inserted inside cylinder 20. Cylinder 20 may then be re-inserted in cups 18 in the position shown in solid lines in FIG. 2.

'Although it is a feature of the present invention that the cups are placed in axial compression, this is not an absolute requirement of the broader concept of the present invention. In the event that no axial compression is employed, cups 18 or cylinder 20 may be counterweighted, if desired, to hold cylinder 20 in one position only when it is not turned.

Note will be taken that any means may be substituted for cups 18 to support cylinder 20. For example, devices having spring fingers to engage the interior or exterior of cylinder 20 may be provided for that purpose.

Although only a few embodiments of the present invention have been described and illustrated herein, many changes and modifications will, of course, suggest themselves to those skilled in the art. The present invention should, therefore, not be limited to the embodiments selected for this disclosure, the true scope of the invention being defined only in the appended claims.

What is claimed is:

1. A credit card l-ist viewer comprising: a pair of leaf supports; a cup at the end of each support, said cups facing each other; means rotatably mounting said cups about their axes on said supports; and a transparent cylinder having its ends in said cups; said cups having circumferential gripping means on the interior thereof to prevent rotation of said cylinder in said cups, said supports being bowed in to supply an axial bearing load on said cups to prevent rotation of said cups without the application of a force thereto; each of said cups having a base and a cylindrical side wall, said side walls having a plurality of inwardly directed, spaced projections thereon to act as said gripping means.

2. A credit card list viewer comprising: a pair of leaf spring supports; a cup at the end of each support, said cups facing each other; means rotatably mounting said cups about their axes on said supports; and a transparent cylinder having its ends in said cups, said cups having circumferential gripping means on the interior thereof to prevent rotation of said cylinder in said cups; each of said cups having a base and a cylindrical side wall, said side walls having a plurality of inwardly directed, spaced projections thereon to act as said gripping means.
